NumPy: Split the element of a given array with spaces

NumPy String: Exercise-10 with Solution

Write a NumPy program to split the element of a given array with spaces.

Sample Solution:-

Python Code:

import numpy as np
x = np.array(['Python PHP Java C++'], dtype=np.str)
print("Original Array:")
print(x)
r = np.char.split(x)
print("\nSplit the element of the said array with spaces: ")
print(r)

Sample Input:

(['Python PHP Java C++'], dtype=np.str)

Sample Output:

Original Array:
['Python PHP Java C++']

Split the element of the said array with spaces: 
[list(['Python', 'PHP', 'Java', 'C++'])]

Python: Tips of the Day

Getting the last element of a list:

some_list[-1] is the shortest and most Pythonic.

In fact, you can do much more with this syntax. The some_list[-n] syntax gets the nth-to-last element. So some_list[-1] gets the last element, some_list[-2] gets the second to last, etc, all the way down to some_list[-len(some_list)], which gives you the first element.

You can also set list elements in this way. For instance:

>>> some_list = [1, 2, 3]
>>> some_list[-1] = 5 # Set the last element
>>> some_list[-2] = 3 # Set the second to last element
>>> some_list
[1, 3, 5]

Note that getting a list item by index will raise an IndexError if the expected item doesn't exist. This means that some_list[-1] will raise an exception if some_list is empty, because an empty list can't have a last element.
